Department of Pathology and Laboratory Medicine, Sinai Health System RCV000904776 SCV001549692 uncertain significance not provided no assertion criteria provided clinical testing The RS1 p.Gln88His variant was not identified in the literature nor was it identified in ClinVar, Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs201680258) and in control databases in 32 of 205243 chromosomes (13 hemizygous) at a frequency of 0.000156 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the European (non-Finnish) population in 31 of 92671 chromosomes (freq: 0.0003345) and the African population in 1 of 18984 chromosome (freq: 0.00005268) but not in the Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other and South Asian populations. The p.Gln88 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and 2 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
